Read this from Daily Mail on bouncing PLOT lol research:
With each step a woman takes, her breasts move an average of 9 cm - not just up and down, but also sideways - in a figure of eight motion. When she breaks into a run, they move up to 15 cm with each stride, if unconstrained by a bra.
This means that during a 1 km jog of 1,320 steps, the breasts of an average C-cup sized women will have independently travelled as much as 0.12 of a kilometre.
One study by Portsmouth University's Research Group in Breast Health - which uses sensors and 3D scanning software to analyse breast motion - monitored the bosoms of two sets of women during brisk walks.
They found that while the young women's breasts mainly moved up and down, the older group's chests moved more in all directions.
Professor Joanna Scurr, a world expert in breast bio-mechanics, said: 'In all women, their right and left breasts move differently, depending on the mass and how elastic they are.
No other part of the female body is more affected by the forces of gravity than the breasts. While an average pair of breasts weighs about 3 lb each, there is very little natural support to hold them up.
